Just like people get sick, after a long time of use, the sprinkler will have some problems. In the face of different symptoms of different patients, the doctor will prescribe the right medicine, but sometimes the cause of the failure does not have to go into the factory. Can solve, but without the guidance of professionals, we can actually use their own methods to find the "sick" symptoms of the sprinkler, and repair some simple faults that can be dealt with. This process we call troubleshooting of the sprinkler. Next, we will introduce the causes of different "symptoms" and their solutions. Failure: Sprinkler cannot absorb water Causes and methods: 1. Check whether the water pump outlet and outlet switch of the sprinkler pump is turned on. 2. The water pump for the sprinkler is a self-priming pump. When it is used for the first time, the water should be poured. 3, check the suction filter in front of the filter if there is debris blocking the inlet. 4. Inspect the water inlet pipe by section to see if it is sealed. 5. The water diversion height of the water pump used by ordinary sprinklers should be less than 5 meters. 6. Check whether the water pump oil seal of the sprinkler is damaged. The leakage of the pump shaft affects its vacuum. Replace the seal. 7, the sprinkler engine speed is too low, can not reach the required degree of vacuum, adjust the throttle so that the speed at about 1700 rev / min, the gearbox may require different engine speed is different. 8. Check whether the power take-off device of the sprinkler works or not. The power take-off and the drive shaft can cause the water pump not to work. 9, check the sprinkler water pump speed is normal, there is no abnormal noise. If you can't move it, there is a lot of debris around the blade. Failure prevention techniques: In addition to avoid long-term idling of the pump in the detection process, causing the pump temperature is too high to affect its life. Fault: Sprinkler cannot water Causes and methods: The water tank of the sprinkler is too dirty, the outlet filter or the pump body is blocked Failure prevention techniques: The use of sprinklers in winter needs to drain the water tank and stagnant water in the pump body, otherwise it may cause the interior of the tank and the water pump of the sprinkler to freeze and crack. Fault: Abnormal motor rotation Causes and methods: 1. No response after power on. Most of them are caused by short-circuiting of power plugs, power outlets, and motor windings. 2, difficult to start or can not start, and accompanied by a "click" sound. During inspection and repair, small bamboo strips can be used to rapidly move the blades according to the running direction. If the motor is quickly operated, it indicates that the starting capacitor or starting winding is damaged. Replace the capacitor with the same capacity or repair the starting winding. If the motor is issued, the motor and the pump head are mostly. Mechanical failure, such as bearing damage, stuck impeller and so on. 3, the motor can run, but the speed is slow, and the chassis is overheated, burned odor. Most of them are caused by the short circuit of the motor windings. The motor should be disassembled and repaired by welding, jumper, isolation, rewinding, etc., depending on the damage. 4, large noise and vibration during operation. Most of the bearings are damaged or the bearing and the chassis are not properly mated. The motor must be dismantled for inspection. If the bearings are damaged, they should be replaced. If the bearings run out of the circle, the pump shell can be mated with the stencil treatment. If the bearings run in a circle, The wear part of the motor shaft is stenciled, and the wear is serious. The repair is performed by first surfacing after welding. Fault: Abnormal water exiting the sprinkler pump head Causes and methods: First check the water pump pump seal, check the power plug should be unplugged, hand to plug the suction port, fill the water pump, with the mouth to seal the exit and blow in the air, observe the pump head is leaking The leaking point is where the seal is damaged. Failure prevention techniques: Common faults include suction pad, outlet pad, and impeller cover pad, which should be replaced during maintenance. If there is no full water phenomenon, the impeller is damaged, the water-retaining partition between the water-absorbing chamber and the outlet chamber is worn out, the pump head is covered with water, and the gap between the impeller and the pump casing is increased. The impeller and the pump casing should be replaced. . When replacing the rake wheel, care should be taken to completely remove the remaining copper blades in the pump so as not to damage the new impeller again. Fault: The chassis is charged. Causes and methods: Most of them are water seal damage, and water infiltrates into the motor through the motor shaft to deteriorate the insulation performance of the motor. Method: Replace the water seal or dry the motor. Failure prevention techniques: Because the water pump is exposed to water for a long time and working in the open air, it is easy to get wet and cause deterioration of insulation performance. In order to ensure personal safety, the self-priming pump of the electric sprinkler should be reliably grounded. Jinan Jing Xun Cnc Equipment Co., Ltd , https://www.jn-jingxun.com
